FTC vs. Open SMTP Relays

HighOrbit writes "Cnet reports on news.com.com that The U.S. Federal Trade Commission, several state Attorneys General, and Australia, Canada and Japan are sending this letter (pdf) to operators of open relay mail servers to educate them on the dangers of open relays and how they help spread spam. Although the letter does not threaten direct law enforcement action, it does let open relayers know that they have been noticed and warned. The threat of being blacklisted has not worked yet, so will this finally convince mail server admins to shut down those open relays?"

    Maybe I'm the only one that had this train of thought, but I'll put it here anyways. I, personally, run a home-based server that runs many services (web, ftp, SMTP and POP3 are some of them).

    The threat of being blacklisted would make me change my ways, as I have nothing to gain and everything to lose should that happen. I would presume the same is true for most sys admins out there, who run *honest* servers.

    Now let's say that the few "Open Relay" servers that are left are threatened, but they don't take action. Pardon my conspiracy theory, but it may very well be that these "innocent" open relays are in fact sponsored by spam clearinghouses, in which case server admins have monetary incentive to NOT close their relays.

    I'd imagine the few open relays that are left are supported by spammers in some way, as they are key in spreading spam, and most people don't want spam passing through their systems anyway, so any anti-spam person would probably close their relays as soon as they are first notified.

    So to relate this to the article, I'd say that a letter from the FTC that doesn't threaten *legal* action will provide no more incentive to these system administrators to close the relays; thus the letters become little more than a waste of paper...

    Just my thoughts on the matter.

      Interesting thought, but I doubt anybody's going to pay to have an open relay stay open. There's just so many of them out there from which to choose! ;)

      I would imagine they all fall into one of the following groups:

      • Insecure default setups
      • Admins who don't know better (or aren't really "admins")
      • Admins that don't give a crap

      Besides, I'd hate to have a business relationship or paper trail with an open relay provider in case it ever becomes possible to sue over an open relay. I'm no lawyer but I'd think you'd be an accessory by paying them to provide a questionable service.

    Rumor has it that there's a whole bunch of open relays out there which are owned by the spamhausen. (I'd love to see some evidence to the contrary, but that's asking proof of a negative, so I won't hold my breath.) If we accept that rumor as fact for the sake of argument, all the FTC letter is going to do is tell said spamhausen that their crap is getting to the target audiences, and they'll happily redouble their efforts.

    It's been said before, but it's worth repeating. The best way to eliminate spam is not to go after the machines (and coincidentally the people in charge of the care and feeding of them). Go after the people and companies hiring the spamhausen...the ones pushing their "herbal Viagara" (sic), pr0n, better mortgage rates, and so forth down the wire and into our overloaded mail accounts. Take away the revenue stream, and all those open relays will go idle until someone puts them to better use (for example, Quake 3 servers).

    Just my two cents' worth...save up the change for a root beer or something.

  6. We did this by DNS-and-BIND · · Score: 4, Interesting
    I worked at a company that ran open relays. I couldn't get them to shut them down, either. It was because we used a web-based email service, and they wanted people to be able to send mail with Outlook using our mail servers. The system was originally implemented on a unix platform by programmers who had mostly worked with windows in their careers. They were pretty clueless about everything...for example, our SQLnet port was wide-open to the world before I got it firewalled off, and the username was the domain name and the password was the company name spelled backwards. I told them about reply-to and other such measures, but was told that was unacceptable, we needed to keep the relays open. One manager was even demoted and eventually let go because he took it on his own authority to close down the relays one weekend because we were being used to spread the Nigerian bank account spam.

    The real problem? Wierd foreign programmers who don't understand How Things Work and moreover don't care, and executives that just want a working system and to hell with being a good netizen.

  7. I don't think it's a admin problem. by BoomerSooner · · Score: 2, Interesting

    It's a protocol problem. SMTP is never going to be good enough. For example, I run qmail, courier, horde/imp. To keep it from being an open relay I use relay-ctrl. However in my testing (to make sure it wasn't open) I found a few very interesting things. On 99% of email servers if you know how to properly input the mail headers you can send anyone an email on that server.

    Granted this isn't an open relay but if you have a list of everyone at intel (or not just figure out their email addresses via a web search). You could easily email all of them anything you wanted (as the spammer) only using their own mail server. I havent tried this on a lot of servers but I have a very high success rate (I only try it with my friends accounts on different servers and I let them know ahead of time so they aren't confused).

    This just helps make my point. Non authenticated SMTP is killing the internet. If the big whigs would come out with a new OPEN protocol (AOL, MSN, Earthlink, ... in conjunction with the OSS community) it would (theoretically) solve a growing problem.

    It would be good for the software makers of email clients/servers as well because they could sell an entirely new set of software.

    I guess I'm just idealistic. I think it can be done.

    Hrrrm. It's actually a bit more difficult than that. Spammers actively look for ways around non-relaying servers, especially in this day of web-based mail forms. We had an incident where a spammer discovered that a poorly coded cgi-form would allow different e-mail addresses to be sent using our web-based mail submittal form. Even though the server was secured against relaying, it wasn't secured against receiving thousands of submittals through its web form. We only noticed it when someone complained to our ISP, who forwarded the notice on to us. We patched it up and sent an apology to our ISP and the original complainer.

    Moral of the story - don't give up complaing to an ISP about spam. You may actually get them to do something about it.

    The spammmer has to open SMTP connections himself to every mail server he wants to spam people on. This takes a lot more resources than putting 1000 addresses on a BCC list and firing the message off to an open relay that does all the hard work.

    I hate to say it, but this isn't nearly as much work as you might think. All it takes is a little special coding and some database maintenance -- something serious spammers would be more than willing to do. By maintaining a table of mail servers for each domain, a program could easily be created that scans through the list of email addresses, selects the correct mail server for its domain and then routes the email directly through that server. The most work would be maintaining the table of mail servers, but they could just target the big ones like Earthlink, AOL, MSN, Yahoo, Hotmail, etc. If this ever happens, you may see a rise in the popularity of Ma & Pa ISPs again.

    On a good note, spammers who directly route through the recipient's mail server will be much easier to track down -- unless they break into another computer system to do their dirty work.
